Mercedes-AMG GT63 S Drag Races Audi RS7 In This Twin-Turbo V8 Showdown

The new Audi RS7 is one of the last four high-performance doors from Ingolstadt to be appreciated by car buyers in the United States. Under his undeniably elegant and aggressive body, he has punch.

The 4.0-liter twin-turbo V8 that powers this monster comes with a peak power of 591 horsepower (441 kilowatts) and 590 pound-feet of torque (800 Newton meters), sent to all four wheels via Audi’s Quattro .

Note that the RS7 Sportback is the most powerful Audi A7 to date.

But the RS7 is not without a worthy opponent. Enter the Mercedes-AMG GT63 S. The four-door coupe is also powered by a 4.0-liter twin-turbo V8 engine, coded AMG M177, developing 630 hp (470 kW) and 664 lb-ft (900 Nm) of torsion – also sent to all four wheels but with a bias at the rear.

With these figures presented, it is obvious that the Audi RS7 Sportback perfectly matches the AMG GT63 S – although that of Stuttgart has a little advantage. It is important to note, however, that the Mercedes is a little heavier than the Audi, the latter having a weight advantage of 55 kilograms (121 pounds).

The Mercedes is also more expensive than the Audi. To be honest, it’s a lot more expensive, but you should all know by now.

As usual, carwow got hold of the two cars for his weekly drag race. Who do you think won this competition? Watch the video at the top of this page to find out.
